Tampa, Florida -- The chief of staff of the controversial New Black Panthers political party is accused of selling a home she didn't own.

40-year-old Michelle Williams was arrested Tuesday night on a charge of Second Degree Grand Theft. She was later released on $7,500 bond.

According to Williams' arrest report, in 2011 David Lee purchased a home for $30,000 using a quit claim deed from Williams through her company, Sunshine's Property Management LLC. Lee said the sale was done under the condition there were no liens or claims to the property.

Lee, however, learned the property was actually owned by somebody else, who allegedly told him Williams was actually helping him with his foreclosure and Williams never owned the property in the first place.

Suspecting fraud, Lee went to police. After a lengthy investigation was turned over to the state attorney's office, charges were filed earlier this week.

Williams, a community activist who is the chief of staff for the New Black Panther Party, came under fire earlier this year when she called for a "dead or alive" bounty on George Zimmerman.

Zimmerman is accused of shooting and killing Trayvon Martin, an unarmed African American teen, during a confrontation in Zimmerman's neighborhood back in February. Zimmerman claims he was defending himself at the time, and for several months no charges were brought against him.

It was during this time that Williams said on a nationally syndicated radio talk show hosted by Bubba the Love Sponge, "Let me tell you, the things that's about to happen, to these honkeys, these crackers, these pigs, these pink people, these ---- people. It has been long overdue. My prize right now this evening is gonna be the bounty, the arrest, dead or alive, for Geroge Zimmerman."

Tuesday night's arrest is not Williams' first brush with the law. Williams, who was previously known as Michelle Conyers, has been arrested on charges ranging from aggravated assault with a handgun to fraudulent use of personal information, fraudulent use of a credit card, petty theft, two previous counts of grand theft, two counts of forgery and exploitation of an elderly person.

She entered guilty pleas to several of the charges and was sentenced to restitution and probation, which she completed successfully. Before Tuesday, she hadn't been involved with the court system since 2005.
